They definitely have three pieces. Russia boasts a platoon of "Armata" tanks

Russian tankers are being trained to operate new T-14 "Armata" tanks. This is indicated by a photo that recently appeared in the public domain. The photo shows three machines, most likely during operations at the testing grounds. These are the only confirmed tanks of this model that the Russian Federation appears to have in active service. However, three tanks are enough to form a platoon.

According to reports from Russian propaganda, the T-14 "Armata" tanks were allegedly "tested" on the front lines during battles with Ukrainian defenders, and then they were withdrawn from use. These tanks were not well received among the Russian military due to their poor technical condition and high unreliability, however, there is a lack of data on what specifically in the "Armatas" was so terribly bothering the Russian tankers. Sources suggest that the Russian Federation had only produced about 20 of these machines.

All indications are that the Russians have not given up and have attempted to improve the T-14. Already a year ago, films from training ranges showing tests of the "Armata" suggested that the engine had been replaced in the vehicle. The original project assumed that the tank would be equipped with the A-85-3A diesel engine with a power output of 1500 horsepower, however, experts suggested that the sound heard in the recordings is more likely from a gas turbine engine.

The engine problem, however, could not be the only flaw with which the designers of the "Armata" struggled. It's worth recalling the breakdown of this vehicle during trials for the Moscow Victory Day parade in 2022. Perhaps the problem with the "Armata" turned out to be so large that the project saw a drain of funds. In September 2023, there was speculation about Russia resuming the production of T-80 tanks in a modified "Burlak" version, which could be a "budget alternative" for the T-14.

Training on a limited number of tanks (remember, we know about 3 in operation) will probably be ineffective when it comes to familiarizing Russian tankers with the operation of the "Armata". The lack of a large fleet of tanks that can be sent to the front, and on some of which the next crews can be trained, means that the T-14 will probably remain in the propaganda form of Putin's "wunderwaffe".
